7750 SR-a4 and SR-a8 Installation Guide

Note:
•
The 7750 SR-a4 chassis requires a minimum of one PSU to operate, but two are
recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two
PSUs to operate, but four are recommended for redundancy.
•
For full redundancy, each PSU module should be attached to an independent power
source with a dedicated circuit breaker. A fully redundant system must be connected to
both DC PSU modules, or both AC PSU modules, or one DC and one AC PSU module.
•
In the event of a PSU module failure, the entire AC or DC PSU must be replaced. There
are no field-serviceable parts inside the PSU.
•
Empty PSU slots in the chassis must be covered by impedance panels. Panels must be
ordered separately. See
for more information.
